You might have noticed an unexplained set of doodles on the Google homepage and a couple tweets from our official Twitter stream, @google, over the last two weeks. On September 5th, we posted a doodle with the abduction of our second 'o' and a coded tweet from its alien captors: 1.12.12 25.15.21.18 15 1.18.5 2.5.12.15.14.7 20.15 21.19, which translates into "All your O are belong to us" (a nod to the Japanese video game, Zero Wing).

Ten days later, the UFO returned. This time, it was to leave its mysterious mark on the fields.

While the link from the doodle to a search for "crop circles" didn't provide any more clues, we also tweeted the lat/long coordinates of Horsell Commons, the location of the first alien landing in H.G. Wells 1898 classic, The War of the Worlds. Some of you figured out what we were doing, but we weren't ready to reveal it all just yet.

Now, we're finally acknowledging the reason for the doodles with an official nod to Herbert George, who would be 143 years old today.

Inspiration for innovation in technology and design can come from lots of places; we wanted to celebrate H.G. Wells as an author who encouraged fantastical thinking about what is possible, on this planet and beyond. And maybe have some fun while we were doing it.

The invasion of the logo by alien crafts and pods makes our series complete, but you'll have to read the book to find out how Wells' story really ends.
